Improve your email performance

Purchased lists are often riddled with spam traps, which are created by internet service providers and blacklist providers to catch spammers. These spammers scrape email addresses from the internet, compile them into lists and sell them to companies — without the email owners’ permission.

Maybe you didn’t purchase a list, but you just haven’t ever validated the email list you compiled. It might be filled with non-existent email contacts, which could come from something as simple as someone making a typo in their own email address when filling out a website form. Or maybe they changed jobs or last names after a wedding and abandoned their old address for a new one.

Emailing spammy or non-existent emails can drive down your email marketing key performance indicators (KPIs), including your open rate, click-through rate and conversion rate. It can also diminish your sender reputation, which is like the “credit score” for your email address.

Improve your email performance and sender reputation by using an email checker that offers bulk email validation.
